Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

1-(2,2,3,3-Tetrafluoro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)ethan-1-one (CAS 540738-37-2) is a high-purity analytical reference standard with the molecular formula C10H6F4O3 and a molecular weight of 250.15 g/mol.

Structurally, 1-(2,2,3,3-Tetrafluoro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)ethan-1-one (C10H6F4O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 250.15 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
